The Z80 only has a 16-bit address space.
My favorite CISC architecture is the 68000 series.
- qwertyuiop924 10y agoYes. But you could install an MMU. The 68k (and it's 8-bit semi-cousin, the 6809) were very nice. However, unlike the Z80, the 6502, and x86, they're no longer being made, and are increasingly rare.

- emptybits 10y agoThe 68k is still being made in the form of the 680x0-compatible line from NXP. http://www.nxp.com/products/microcontrollers-and-processors/more-processors/coldfire-plus-coldfire-32-bit-mcus/68kmpus-legacy/m680x0:DR68K68KM68X0 http://www.nxp.com/products/microcontrollers-and-processors/... They're in the "legacy" line and labelled "not recommended for new design" but I think that's just design opinion and doesn't imply it's no longer made. I'm sure this video has done the HN rounds before. It's a slow but fascinating watch.
